GASIFIER Filed March 23. 1929 Patented ct. 6', 1931 TIMOTHY G. SULLIVAN,0F PORTLAND, OREGO GASIFIEB My invention relates to gasifiers ingeneral, and particularly to such devices adaptable to internalcombustion engines for preparing the fuel mixture therefor. y

'The object of my invention is to provide a device that will deliver aperfect gas to the engine instead of the mechanical mixture of sprayheretofore used. I accomplish this object by means of the constructionillustrated in the accompanying drawing, which is a part of thisapplication for Letters Patent, like characters indicating like partstherein, and which is a sectional elevation of my device.

In general my device consists of an electrical heating unit throughwhich the liquid fuel is passed on its way to the Venturi tube and theintake manifold of the engine.

In the drawing 1 represents the upper portion of the cylinder block andthe cylinder head of the engine, and 2 the intake manifold with theusual buttery vvalve 3 therein. In the lower part of said intakemanifold is the Venturi tube 4. Within said Venturi tube is positionedthe fuel nozzle 5, which nozzle is a prolongation of a coil of pipe 6embedded in an insulating medium of high heat conductivity, such as aglass cylinder 7 or the like.

Wound upon said cylinder is an electric wire 8 in series with a sourceof electric current, such as the battery 9. Surrounding said wire 8 isan insulating sleeve 10, and the said sleeve together with theelectrical wire and the glass cylinder is enclosed in a shell 11, beingheld therein by a cap 12. The upper portion of said shell is threadedinto the lower portion of the intake manifold at the Venturi tube, asshown at 13.

T'he upper portion of said shell is perforated with orifices 14, and aclosure member V 15 is rotatably mounted thereupon, and is provided withcorresponding orices, for the urpose of opening or closing said orifices14 y rotating said closure member into any Application filed Hatch 28.1929. Serial No. 349x383.

operated from the engine in any suitable 'manner, such not being a partof the present invention and being well known to the art is notillustrated in the drawing. 1

An arm 21 is provided for operating vthe buttery valve 3, and a similararm 22 is provided for operating the regulating valve 16. Said arms areconnected by a rod 23, which is rendered adjustable as to length byhavin a portion thereof hollow, the two portions eing secured togetherby means of a set screw. A further arm 24 is connected to the valve 16to operate the same, and is to be connected to operating mechanismconveniently located respective to the operator of the engine, suchoperating mechanism being well known to the art is not illustrated inthe drawing.

My invention may be made of any size, and constructed of any materialsdeemed convenient and suitable for a device of this character, and whileI have illustrated and described a form of construction and arrangementof parts found desirable in materializing my invention, I wish toinclude in this a plication all mechanical equivalents and su stitutesthat may fairly be considered to come within the scope and purview of myinvention as defined in the appended claim.

Having disclosed my invention so that others may be enabled to constructand to use the same, what I claim as new, and desire to secure byLetters Patent is: l

In a gasifier for internal combustion engines: a Venturi tube ;.a nozzlewithin said tube; an electric insulating member of high heat conductivia coiled pipe embedded within said mem r and connected with said nozzle;an electric heating coil upon said member and connected With a source ofelectric current; an insulating sleeve surroundingsaid heating coil; ashell encasin said 5 sleeve and connected with said Venturi tube; airadmitting orifices in said shell adjacent said Venturi tube; a closuremember for said orifices mounted upon said shell; and means for1 forcingliquid fuel through said pipe co1 10 In Witness whereof I claim theforegoing as my own I hereunto aHX my signature at Portland, county ofMultnomah, State of Oregon, this 18th day of March, 1929.
